Application filed August '15, 1924'. Serial No. 732,248.

My invention relates to improvements in fabric cleaning machines and 1s part cularly designed for cleaning rugs and other heavy fabrics. I I q n One of the objects of my invention is to provide a machine'in which the rug or other articles to be cleaned may be thoroughly drenched with cleaning mud and at the same time scoured without WIlIlkllIlg or folding the rug and in which be reclaimed.

Forthe purpose offldisclosing my invention I have illustrated one embodiment thereof in the accompanying drawings in which,

Fig. 1 is a side elevation of, a machine em bodying' myinvention; .7 a I Fig. 2 is a front end view thereof, and

Fig. 3 is a detail section on the line 3'3 of the embodiment. of the machine illus trated I provide a suitable supporting frame 1 comprising the two side bars 2 which may be formed of channel iron or thevlike and which are provided at suitable intervals with supporting legs 3. These side bars, on their inner faces, at suitable intervals, are provided with bearing brackets 4, in which are mounted rollers 5. Mounted to reciprocate on the rollers of the. main frame is a carrier frame 6 comprising the side members pref-I erably formed of angle irons, the horizontal members 7 of which are provided on their under faces with rails 8 co-operating with the grooved rollers 5 of the main frame. The side rails of the carrier frame are secured together at their ends by means of cross braces 9 and disposed at suitable intervals along. the carrier frame, being journallcd in the vertical members 10 of the side members of the carrier frame, are transversely extending shafts 11 carrying at their opposite ends, to rotate therewith, eccentric cams 12. These shafts are adapted to be rotated simultaneously and to this end each shaft is provided at its center with a worm wheel13, each operated by a worm 14. The worms 14 aremounted on'a longitudinally extending shaft 1-5 journalled in the cross braces 9 andprovided at its front end with an operating wheel 16 for rotating the shaft.

the cleansing fluid may thereis a spray pipe extending va suitable supply pipe 31 and, if desired,

upon this frame is a series of spaced longitudinalbars 20 which in turnhave mounted thereon a wire mesh 21, this arrangement forming a support for the rugs to be cleaned I and at the same time forms a drainage surface to permit the passage therethroughof the cleaning fluid. The wire mesh is provided at suitable intervalswith small 11E",- wardly extending pins 22 which retainthe article to be cleaned on the platform or rug frame i g l i Mounted on the under side of the carrier frame 6 is a drip pan 23, the sides of which are provided withhorizontal flanges 24 for securing to the horizontal side members 7. The forward end of this pan is closed and the bottom inclines downwardly from the front to the rear of the carrier frame, the pan being of the same length as the carrier frame. c

Mounted in the main frame and below the carrier frame pan is a drain pan 25'which at all. times will receive the drainage from the pan. 23 and has its bottom sloping toward a central point 26 atwhich point there is provided anoutlet pipe 27 preferably lead: ing to a clarifying-tank. I

Above the carrier frame there, is provided a housing 28 closed at its'rear end and hav-, ing at its front an opening just sufficiently large to accommodate the passage of the carrierframe. ,-lVithin this housing and at the forward end thereof is mounted a rotat able cleaning brush 29 preferably adapted to rotate in the direction indicated by the arrow and immediately above the brush 29 transversely of the housing and adapte to deliver the cleaning fluid immediately above and slightly in front of the'cleaning brush, The fluid is delivered to this spray pipe by additional spray pipes 82 may be extended, across the housing at suitable intervals. At the forward portion of the :housing and to the rear of the brush 29 there provided a baflie plate 33.

is preferably In operation the carrier platform is run out of the housing to the forward end of the frame, either by hand or a suitable motor operated reciprocating mechanism. The rug to be cleaned is unrolled on the wire mesh in a perfectly flat position being held against displacement by the pins 22. After the rug has been placed in position the height of the carrier frame is adjusted to bring the rug into proper contact with the brush 29, by means of the worms and gears 13 and 1.4. After suitable adjustment,-the cleansing fluid is admitted through the spray pipe and the carrier platform or frame moved into the housing and beneath the brush. As the rug passes beneath the brush it is thoroughly drenched with the cleansing fluid and brushed so that all dirt is removed and the cleansing fluid drains through the carrier platform into the drip pan 23 and out the rear end of this drip pan into the drain pan 25 from whence it is drained to a suitable settling tank.

The rug may be reciprocated beneath the brush and cleansing fluid as often as is necessary to thoroughly clean the same.
